The marks you get with INGInious are not equal to the marks you'll get for the project.
You can download the project instructions here. The extractor executable can be downloaded here for the x86_64 architecture, or here for the Apple Silicon chip. It is a toy example to help you develop your fuzzer.
You must first register to a group on INGInious with your partner to be able to submit.
This task will test if your archive respects the format. After the deadline, your fuzzer will be tested on a different extractor binary, containing more bugs than the toy example.
Only your last submission will be taken into account.
